Seed collection and propagation
Collect seeds between September and December. Collect mature capsules that are drying off, turning pale brown with hard, dark seeds inside. Place the capsules in a tray and leave to dry for 1-2 weeks. Then rub the dried capsules with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. This species has physical dormancy that needs to be overcome for the seed to germinate.
